Katy Perry's Seventeen cover story

On her teen skin problems popping up: "I was on Warped Tour last year, during the summer, and I literally broke out like I had never broken out before. It was at the beginning of my career and you can see pictures of me from then until now it's total night and day. I just started being healthier to my skin. But I remember covering my face with my hair because I was so self-conscious I wouldn't even look my boyfriends in the eyes because of it! And I'm really not a self-conscious person, but that did me over."
